Specification of Letters Patent.

Application led October 9, 1913.

Patented Aug. 11, 1914:. Serial No. 794,275.

and PERcY H.` D. WALKER, citizens of the' United States, residing at Meriden, county of New Haven, State of Connecticut, have invented an Improvement in Swivel-Vises, of which the following is a specification.

rlhis invention relates to the construction of swivel vises and has for its objects to simplify and cheapen their construction and to improve their operation in use, more e'specially to provide a base which may be cast without diliiculty, no coring being required and the parts being so constructed that the bolts are permanently seated and have no sliding movement, thus avoiding the possibility of the bolt heads seating on uneven surfaces and rendering machining of the base unnecessary. With these and other objects in view we have devised the novel swivel vise which we will now describe, referring to the accompanying drawing forming a part of this specification and using reference characters to indicate the several parts.

Figure 1 is an elevation of our novel vise complete; Fig. 2 an inverted plan view thereof, the sliding bar and parts carried thereby being omitted; Fig. 3 a section on the line 3*-3 in Fig. 1; looking in the direction of the arrows; and Fig. 4 is an end view of the locking plate removed.

10 denotes the body of our novel vise which is provided with a circular flange, 11 adapted to rotate on a base 12, 13 the fixed jaw, 14 the slide bar, 15 the movable jaw carried by the slide bar, 16 the screw, 17 the nut which is engaged by the screw, 18 the head of the screw and 19 the lever. The parts above the base will not be described in detail, as specifically they form no portion of the present invention. The base is provided with a central opening 20 and in its underside with a circular recess 21 of greater diameter than the opening, leaving a circular flange 22 overhanging the recess. The body is provided with a downwardly extending center pin 23 which engages a central hole in a locking plate 24E which is adapted to rotate with the body and jaws in recess 21. The locking plate is provided on its under side with pairs of lugs 25 adapted to receive between them and hold against rotation the angular heads of y heads retained against bolts 26. These bolts pass upward through holes in the locking plate, through opening 2O in the base, without engagement therer with, and through holes in flange 11 of the body, and are tightened up to hold the body and plate together and to lock the body in any required position on the base by means of nuts 27. The base is provided with ears 28 through which bolts, not shown, pass to secure the vise in place on a bench or elsewhere.

The operation of our novel vise is precisely the same as with ordinary swivel vises. To adjust the position of the body and jaws relatively to the base, it is simply necessary to loosen the nuts and turn the body and jaws to the required position in which the body is locked by tightening up the nuts.

Our invention enables us to produce a strong and durable vise which is easily and quickly adjusted to the required position and may be produced at a greatly reduced cost owing to its simplicity of construction. The heads of the bolts do not bear on the base but upon the locking plate which has relatively large Contact surfaces with the base, and causes the parts to work easily while avoiding the necessity for fine Work in finishing the parts.

Having thus described our invention we claim:

A vise of the character described, comprising a base having an opening through it and an overhanging flange, a body having a flange resting on the base flange and a downwardly extending center pin, a locking plate under the base flange having a hole engaged by the center pin and pairs of lugs at opposite ends, bolts having angular rotation by said lugs, said bolts passing through the locking plate, the opening in the base and the body flange, and nuts engaging said bolts and bearing on the body flange to lock the body at any required adjustment.

In testimony whereof we affix our signatures in presence of two witnesses.
